Abstract: The present invention allows for the automatic dialing of local and long distance calls in the United States, as well as automatic dialing of international calls. The automatic dialing feature is accomplished, in part, by implementing a computerized data base grouped in N—files. These files may be searched by the computer system during and after the caller dials a number. If the dialed number matches one of the numbers in the files, the system may automatically out-dial the dialed number.

Abstract: The present invention comprises four principle elements: (1) a telephone instrument; (2) a computer; (3) an automatic dialer; and (4) a telephone line. These elements allow for automatic dialing of local and long distance calls in the United States, as well as automatic dialing of international calls. The automatic dialing feature is accomplished, in part, by implementing a computerized data base grouped in n-files. These files may be searched by the computer system during and after the caller dials a number. If the dialed number matches one of the numbers in the files, the system may automatically out-dial the dialed number.

Abstract: A communications distribution system is disclosed for facilitating the handling of telephone calls within a plurality of groups. Each of the groups includes a line group and a channel group interconnected by an anticipatory call distributor (ANCD) for determining the availability of channels for connecting to a line from the associated line group, and for reassigning channels to other groups as long as a certain minimum capacity is maintained in each group. The ANCD also anticipates whether any channels are expected to become available within a predetermined period. In response to channel availability, or to a channel that is expected to become available, a priority and availability logic sets an appropriate status register, which is checked by switching command logic.

Abstract: A rotary turbine employs rotors that are rotated primarily by the frictional forces of a pressurized medium flowing through a gap that separates the rotors from the stationary housing. The rotors are coupled to a source of pressurized medium that creates a medium flow through the gap. The frictional forces between the flowing medium and the rotors create a torque that rotates the rotors. A compressor is formed of a rotor assembly that includes first and second counter-rotating rotors having substantially smooth surfaces. The rotors are separated by a gap that allows the medium to flow therethrough, with the surface of at least one of the rotors contacting the medium, such that the flow of the medium through the gap is induced by surface friction between the contact surface and the medium.

Abstract: A rotary turbine including a source of a pressurized medium and a rotor assembly. In one embodiment, the rotor assembly includes first and second rotors, and the surface of each rotor is substantially smooth. The pressurized medium flows between the rotors, turning the rotors. The smooth rotor surfaces do not cause substantial turbulence in the medium. Accordingly, the exit velocity of the pressurized medium is maintained at a substantial higher level than if the rotors included blades or other protrusions extending outwardly.
